The role of sucrose and sucrose synthetase in carbohydrate plant metabolism
Copyright policy )The role of sucrose and sucrose synthetase in carbohydrate plant metabolism
1. The role of sucrose as a controlling factor of metabolic activities in the plant cell is discussed. 2. The problem of differentially modifying the rates of synthesis and cleavage of sucrose catalyzed by sucrose synthetase was studied using phenylglycosides, sugars, and divalent cations. 3. Trypsin action on sucrose synthetase resulted in an enzyme which retained the synthetic activity but lost about 80% of the cleavage activity. Saturation curves for sucrose which were hyperbolical for the native enzyme, were modified to sigmoidal for the trypsin treated enzyme.
